Configuring Basic IPv6 Functions
509
■
EUI-64 format: When the EUI-64 format is adopted to form IPv6 addresses, the
IPv6 address prefix of an interface is the configured prefix and the interface
identifier is derived from the link-layer address of the interface.
■
Manual configuration: IPv6 site-local addresses or aggregatable global unicast
addresses are configured manually.
IPv6 link-local addresses can be configured in either of the following ways:
■
Automatic generation: The device automatically generates a link-local address
for an interface according to the link-local address prefix (FE80::/64) and the
link-layer address of the interface.
■
Manual assignment: IPv6 link-local addresses can be assigned manually.
Follow these steps to configure an IPv6 unicast address:
n
■
After an IPv6 site-local address or aggregatable global unicast address is
configured for an interface, a link-local address will be generated automatically.
The automatically generated link-local address is the same as the one
generated by using the
ipv6 address auto link-local
command. If a link-local
address is manually assigned to an interface, this link-local address takes effect.
If the manually assigned link-local address is removed, the automatically
generated link-local address takes effect.
■
The manual assignment takes precedence over the automatic generation. That
is, if you first adopt the automatic generation and then the manual
assignment, the manually assigned link-local address will overwrite the
automatically generated one. If you first adopt the manual assignment and
then the automatic generation, the automatically generated link-local address
will not take effect and the link-local address of an interface is still the manually
assigned one. If you delete the manually assigned address, the automatically
generated link-local address is validated.
